Hunting Shirt Fit Guide: How to Pick the Right Size for Layering

Use your real chest and sleeve measurements, not your street size, to pick a hunting shirt that layers cleanly. Six steps for a quiet, non-binding fit from base layer to outer shirt.
Quick answer
Size a hunting shirt off your measured chest, not the size you wear in a t-shirt, and leave roughly a fist of room at the chest for a base layer plus a light midlayer. The sleeve should reach the wrist bone with your arm bent, and the hem should stay put when you reach overhead. If you plan to wear the shirt over a puffy, size up one; if it is your outer layer on mild days, stay true to your measurement.
Most hunters buy a shirt in their everyday size, wear it once with a pack on, and discover the shoulders bind and the hem rides up. The problem is rarely the shirt. It is that the shirt was chosen for how it looks standing still, not for how it moves under a pack, over a base layer, or under a midlayer.
This guide walks through a repeatable fitting process you can do at home with a tape measure and the layers you actually hunt in. It applies to any hunting shirt, including casual options like the Icon Logo Hoodie 2.0 and the Float Plane Tee, which work as camp and shoulder-season layers rather than technical outerwear.

Start with your body measurements, not your tag size
Measure your chest at the fullest point, keeping the tape level and snug but not tight. Measure your sleeve from the center back of your neck, over the shoulder, and down to the wrist bone with your arm slightly bent. Write both numbers down. These two measurements, plus your torso length, are the only ones that matter for layering.
Brand size charts vary more than hunters expect, and a shirt cut for layering is often built with extra room in the chest and shoulders. Comparing your measured chest to the chart is more reliable than assuming you are always a large. If you are between sizes, the next step tells you which way to go.
- Measure over a thin base layer, not a bulky sweatshirt.
- Have someone else measure your sleeve if you can; self-measuring the back is where errors creep in.
Decide what the shirt is for before you choose a size
A shirt worn as a base layer should sit close to the body so it can move moisture and slide under a midlayer without bunching. A shirt worn as an outer layer over a base layer and light insulation needs extra chest and shoulder room so it does not compress the layers beneath it. Those are two different fits, and one shirt cannot do both well.
Be honest about your typical hunt. If you run warm and hunt early season, a trimmer fit is more comfortable. If you sit late-season or glass for hours, you want the roomier cut. Write down which role the shirt fills before you order.
- Base layer role: close fit, minimal excess fabric.
- Outer shirt role: room for one midlayer, no more.
Test the reach and the pack strap check
Put the shirt on over the layers you expect to wear, then reach both arms straight overhead and to the front like you are grabbing a branch. The hem should stay roughly at your belt line, and you should not feel a hard pull across the upper back. If the shirt rides up to your ribs, it is too short or too tight in the chest.
Next, put your pack on and clip the sternum strap. The shirt should not bunch under the shoulder straps or restrict your breathing. A shirt that feels fine in the mirror can fail this test in ten seconds, which is why it is worth doing before you cut tags.
- Reach overhead, then squat and stand. Watch the hem.
- If the collar pulls against your throat with the pack on, size up.
Match sleeve length to your shooting position
Sleeve length matters more in a hunting shirt than in a casual one because your arms are bent when you glass, call, or shoot. A sleeve that ends at the wrist bone with your arm straight will crawl up your forearm when you bend your elbow. Aim for the sleeve to reach the wrist bone with your arm bent about 45 degrees.
If the sleeve is too long, it catches on the string or the release and gathers under a jacket cuff. If it is too short, your wrists are exposed when you are glassing in cold air. Check both arms; most people have a slightly longer dominant arm.
- Bend your elbow to 45 degrees and check where the cuff lands.
- Roll the cuff once if it is borderline, but do not rely on that for a cold-weather layer.
Check the hem, torso length, and how it sits under a belt
A hunting shirt should stay tucked or stay put, depending on how you wear it, without constant adjustment. If you tuck it, the hem needs enough length to stay in your waistband when you bend. If you wear it loose, it should not hang so low that it catches on your hip belt or a game bag.
Torso length is the spec most size charts leave out, which is why trying the shirt with your belt and pack is more useful than reading numbers. If you cannot try it in person, compare the listed back length to a shirt you already own that fits the way you want.
- Bend forward and touch your toes. The hem should not expose your lower back.
- If you wear a hip belt, make sure the shirt does not bunch under it.
Layer up in the order you will actually wear it
Build the full stack: base layer, hunting shirt, midlayer, and shell if you use one. Each layer should slide over the one below without dragging it up. If you have to fight the shirt over your midlayer, the shirt is too trim for that role, and you will be uncomfortable within an hour of hiking.
This is also the moment to check that you can still shoulder a rifle or draw a bow. Extra fabric in the chest and shoulders is fine; extra fabric in the forearms and cuffs is not, because it snags. Adjust the size or the layer stack until both checks pass.
- Put every layer on in order, then move around for two minutes.
- If the shirt is the problem layer, change the shirt, not the midlayer.
The six-step hunting shirt fitting process
- Measure chest and sleeve: Measure your chest at the fullest point and your sleeve from the center back of the neck to the wrist bone with the arm slightly bent. Write both numbers down. Checkpoint: if your chest measurement is within an inch of a size boundary, plan to size up for layering.
- Assign the shirt a role: Decide whether it is a base layer, a standalone outer shirt, or a layer under a midlayer. Each role needs a different amount of chest room. Checkpoint: one shirt should not be expected to do all three roles.
- Do the reach test: Wear the layers you plan to hunt in, reach overhead and forward, and watch the hem and shoulders. Then put your pack on and clip the sternum strap. Checkpoint: hem stays near the belt line and breathing is unrestricted.
- Set sleeve length in a bent-arm position: Bend your elbow to about 45 degrees and confirm the cuff reaches the wrist bone. Check both arms. Checkpoint: no cuff gathering at the forearm and no exposed wrist when glassing.
- Verify hem and torso length: Bend forward and touch your toes. The hem should not expose your lower back, and it should not bunch under a hip belt. Checkpoint: if the size chart omits back length, compare against a shirt you already own.
- Build the full layer stack: Put on base layer, shirt, midlayer, and shell in order. Move for two minutes and check that you can shoulder a rifle or draw a bow without snagging. Checkpoint: if the shirt drags on the layer below, it is too trim for that stack.
Product facts that affect fit
- Icon Logo Hoodie 2.0: Based off the original Icon Logo Hoodie, the 2.0 version is designed for versatile wear and transitions from casual outings to relaxing after a day in the field. It is a camp and travel layer rather than a technical midlayer, so fit it for comfort over a base layer, not for a full insulation stack.
- Float Plane Tee: The Float Plane Tee uses 100% preshrunk cotton with a cut the catalog describes as possibly the most comfortable shirt in your closet. Preshrunk cotton holds its size better after washing, so your measured fit should stay consistent, but cotton is a poor base layer for sweat-heavy hunts.
A hunting shirt fits right when you forget you are wearing it under a pack, in a glassing position, and in the layers you actually hunt in. Measure first, test the reach and the sleeve bend, then adjust the size or the layer stack until nothing binds. That five-minute process saves you from a season of adjusting your collar instead of glassing.
